For temperatures, zero is an arbitrary reference point, depending on which scale is used. For Celsius, zero is assigned the the temperature at which water freezes. So temperatures which are colder than this temperature will be negative values, and temperatures warmer will be positive values. Fahrenheit uses a different reference point for zero, but similar principles apply.
Units are the same. Temperatures in kelvin are 273 more than celsius temperatures.
Negative 1 Celsius is warmer, or you might say, less cold!
-12
Yes, they can. Centigrade (Celsius) can go as low as -273.15 degrees C. The same temperature on the Fahrenheit scale is -459.67 degrees -- both indicate absolute zero (0K). A notable difference caused by having "degrees" of two different sizes and definitions is that negative temperatures on Celsius indicate "below the freezing point of water" (0 degrees C), while below freezing on the Fahrenheit scale includes positive values from 31 down to 0, the freezing point being 32 degrees F.
Temperature in Celsius can be negative. 0 degrees is freezing point in Celsius, so it is possible to get -1, -10 degrees, etc. However, not all temperatures in Celsius are negative.
No. There are no negative kelvin temperatures.
Kelvin scale

First of all, Kelvin absolute zero = -272 degrees Celsius. Secondly, the set of real numbers which contain Celsius numbers and negative Fahrenheit numbers are as follows: Negative X Fahrenheit would = -1 to -31 (because two negatives make a positive, and this would also be consistent with temperatures in the range of 1 to 31 degrees Fahrenheit, along which range all of the Celsius numbers are negative). So, 1 deg F to 31 deg F would then correlate with negative Celsius temperatures (but since we are using the numbers -1 to -31, this would correlate to positive X Celsius). Thus, the range of Kelvin temperatures would be 273 to 304. The reason for which the answer is somewhat convoluted is due to the fact that there do not exist any negative Fahrenheit temperatures for which Celsius temperatures are positive. Thus, negative numbers have to be used in order to "turn the equation around", so to speak, because there is a range of temperatures (1 to 31, in real numbers) Fahrenheit, for which Celsius temperatures are below zero, or in the negative ... due to the fact that deg 0 deg C = 32 deg F.
The Kelvin scale has no negative values because 0 K is absolute zero, no motion.
The two scales intersect : -40 °C is the same temperature as -40 °F This is due to the offset of water's freezing point to 32 °F. Between 32°F and 0°F, the Fahrenheit temperatures are positive while the Celsius temperatures have already moved into the negative. By the point -40°, the larger intervals marked by the Celsius degrees have been "overtaken" by the smaller Fahrenheit intervals. Below this point, negative temperatures in Fahrenheit have larger values than the corresponding Celsius values, just as do all Fahrenheit temperatures above 0°C.
Temp in Kelvin = Temp in Celsius + 273.15° Have a look at Absolute Zero on Wikipedia.
The alcohol thermometer is used to measure temperatures from negative 115 degrees Celsius to 785 degrees Celsius. It measures the freezing point and boiling point of alcohol.
Celsius is a scale of temperature. Its range includes both positive and negative numbers.
Units are the same. Temperatures in kelvin are 273 more than celsius temperatures.
